Description
Technical field
The utility model is related to a kind of automobile chassis suspension structure-design technique field, more particularly to automobile integral bridge type
Rear suspension structure.
Background technology
Suspension is all force transmission connections between the vehicle frame (or bearing-type vehicle frame) of automobile and vehicle bridge (or wheel)
General name, the main function of suspension is a shear force and torque that transmission is acted between wheel and vehicle frame, such as support force, brake force
With driving force etc., and relax the shock loading that vehicle frame is transmitted to by uneven road surface.Decay is thus caused to be vibrated, ensures occupant's
Comfortableness, the dynamic loading of reduction goods and vehicle in itself.Typical automotive suspension structure is by flexible member, damper and guiding
Mechanism etc. is constituted, and buffering, the transmission effect of vibration damping and power are played in this three part respectively.Most suspensions more have helical spring and
Shock absorber structure, but the guiding mechanism difference of different types of suspension is very big, and this is also the core component of suspension property difference.
Two kinds of rigid axle suspension and independent suspension can be divided into according to structure difference.
And rigid axle suspension mainly has both to plant form:1) the overall back axle rigid axle suspension of longitudinal steel plate spring type；This hangs
Frame form relaxes impact and the vibration aspect poor-performing in decay analysis of wheel vertical direction, largely effected on when by uneven road surface
Vehicle ride performance and riding comfort, vehicle noise, vibration and sound vibration roughness (Noise, Vibration,
Harshness, abbreviation NVH) performance is very low.In addition, there is " axle steer " in the monoblock type rear suspension structure, if longitudinal steel plate
If the fixed hinge end arrangement of spring suspension is unreasonable, it will vehicle is produced oversteering, vehicle drive security is influenceed.
2) damper, helical spring separate the overall back axle rigid axle suspension of trailing arm type of longitudinally asymmetric arrangement, and the suspension form is relatively simple
It is single, but the structure unsprung mass it is larger when, ride comfort is also poor, because helical spring is subjected only to vertical load, therefore, the suspension
Structure anti-side is inclined poor-performing, also influences vehicle riding comfort security.
Therefore, based on improve vehicle rear axle spatial arrangement structure, improve back axle wheel hop space, it is empty to optimize back axle
Between and loss of weight it is cost-effective be target, the designer of this area is badly in need of a kind of automobile integral bridge type rear suspension structure of exploitation.
